sToPPER Fon BOTTLES. Y

SPEGIFIGATION forming part of Letters Patent No. 694,013, dated February25, 1902.

Application ledAugnst 25,1899. Serial No. 728.433. (No model.) i i Toall whom, it may concern.-

Beit known that I, JOHN A. HAYES, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Stoppers for Bottles, of which the following is aspecification.

My invention relates to an improved construction of stopper for bottles,the same being so arranged as to be adaptable to the necks of bottles ofvarying diameters and that when in position in the neck it will bepositively held against accidental displacement, but mayV be readily andquickly removed when desired.

The object of my invention is to produce a stopper of this characterwhich shall be simple and inexpensive in construction and which shall beparticularly effective in connection with bottles containing gaseous oreffervescent liquids, such liquids having heretofore been retainedWithin the bottles by means of corks or Stoppers, which in turn havebeen wired or otherwise fastened to prevent their accidental removal.

My invention consists, substantially, of the combination with the neckof the bottle, the

- mouth of said bottle being formed with an internal tapering chamberwhose diameter is greater at the bottom than at the top, a ilexible corkadapted to said chamber and having a central bore through which theliquid may pass, and a screw-stopper adapted to said bore, whereby whenin position in the bottle the same will' be effectively sealed and theWhole secured against accidental displacement.

My invention further consists of the novel features of construction andarrangement of parts, all of which will be hereinafter fully described,and particularly pointed out in the appended claims. Figure 1 representsa central section of a bottle, showing my improved stopper in positiontherein. Fig. 2 represents a similar view showing the screw-stopperremoved. Fig. 3 represents a transverse section taken on the line a: ocof Fig. l.

Similar reference-numerals indicate corresponding parts in all theigures of the drawings.

' Referring to said drawings, 1 designates a bottle the body portion oflwhich maybe of any desired shape or conguration, but the mouth thereofis provided with a chamber 3, whose diameter at the bottom is slightlygreater than at the top.

4 designates -ribs which are formed in the chamber 3, said ribsfollowing the inclination of the wall of the chamber and terminating 6oat a shoulder 5, against which latter the lower end of a cork 6 abuts.The exterior of the cork is made to conform with the shape of thechamber 3 and is provided with grooves adapted't-o the ribs 4, so thatwhen it is in 65 place therein it will be evident that it cannot berotated or readily removed Without the exertion of considerable force.As shown in the drawings, the cork is provided with a central bore 7,which is tapered and is adapted to 7o receive therein the threaded shank8 of a stopper 9, which latter When in applied position serves to expandthe cork, so as to make its exterior impinge the wall of the chamber 3,thus more securely keeping the same in posi- 7 5 tion. The head of thestopperis scalloped or milled and is of such shape as to be easily andfirmly grasped by the fingers during the operation of inserting orremoving the stopper. During such operation it Will be evi- 8e dent thatthe ribs 4 above lreferred to will prevent a rotative movement of thecork 6.

In practice the cork 6, which, as before mentioned, is provided withgrooves to correspond with the ribs 4, is forced intothe chamber 3,where it shall permanently remain, and the lower end of said cork isrounded, as at 10,'in order that thecontents of the bottle may passfreely thereo'ver into and through the central bore 7, as will beapparent.

Having thus described my invention, what I claim, and desire to secureby Letters Pat ent, is as follows: v

l. A stopper for bottles, comprising a tapering cork, the diameter ofwhichvis greater 9 5' Vat the bottom than at the top, andvbeing adaptedto fit into a correspondingly-tapered chamber in thel mouth of thebottle, said cork being provided with a central bore, the Wall of whichis tapered or disposed oppositely to ioo v the external taper of thecork, the said cork having anirregular external configuration, and athreaded stopper adapted to said bore.

2. A stopper for bottles comprising a tapei-ing cork having a pluralityof external grooves, said cork being larger in diameter at lthe bottomthan at the top and being adapted to t a correspondingly-shaped chamberin the mouth of the bottle, said chamber being provided with ribs whichenter said grooves in the cork and prevent rotative movement thereof,said cork being provided with a eenl[ral bore, the Wall of which istapered or disposed oppositely to the external taper of the cork, and athreaded stopper adapted to the bore in said cork.

3. A stopper for bottles, comprising a tapering cork having a pluralityof external grooves, said cork being larger in diameter at the bottomthan at the top an d being adaptthreaded stopper adapted to the bore insaid cork.
